Chapter 3: Things To Consider Before Using Your Module 21
Output Image - Configuration Words
Thirty-two (CTR-8) or sixteen (CTR-4) words of the SLC processor’s
output image table are reserved for the module. For the CTR8, output
image words 0-31 are used to configure input channels 0-7. For the
CTR4, output image words 0-15 are used to configure input channels 0-4.
Each output image word configures a single channel, sets the preset, limit
and scale factors and can be referred to as a configuration word. Each
word has a unique address based on the slot number assigned to the
module.
Example Address - If you want to configure channel 2 on the module
located in slot 4 in the SLC chassis, your address would be O:4.4.
